Purchased the sleeve yesterday for my iPad Pro 9.7 with smart keyboard, silicone case back and apple pencil. The fit is perfect and I can easily retrieve the iPad. Also the profile is a lot slimmer than the Incase slim sleeve with pencil slot case I was using before.

I have the 10.5 inch iPad Pro and the Smart Cover (not keyboard). I can confirm that they fit wonderful and snug in the leather sleeve, however, this makes me think that the Smart Keyboard would start stretching the leather too much and make it very hard to get in and out.
